When I tried this product I was impressed by its sturdy build and reliable performance. It smoothly holds 1-inch diameter threading dies in place, making my threading work more efficient and precise. The holder`s compact size is also a plus as it doesn't take up much space in my toolkit .However, it would be great if it could accommodate larger diameter dies as well. overall, I am satisfied with this product and would recommend it to OTHERS in the cutting tools industry..
